Abstract (en)
The machine (10) for measuring and mathematically defining the surface of three-dimensional models comprises a robotized support (20) having at least three degrees of freedom, provided with actuation motors and position transducers, to support and position, in any point of space and with any orientation, a laser distance device rigidly coupled to the support (20). An electronic control unit (30) controls the movements of the robotized support (20) according to electric signals arriving from the laser distance device and from the position transducers, and an electronic processing unit (40) memorizes on a magnetic support numeric information corresponding to the coordinates of points on the surface (S) to be measured.
